$ sudo modprobe ax88179_178a
modprobe: ERROR: could not insert 'ax88179_178a': Invalid argument

$ dmesg # relevant part
[ 1827.985623] BPF: type_id=1113 bits_offset=0
[ 1827.986241] BPF:

[ 1827.986693] BPF:

[ 1827.986852] failed to validate module [ax88179_178a] BTF: -22
```

### Expected Behavior

I expect the module to be loaded and useable after `modprobe`.

### Actual Behavior

An error occurs:

```shell
$ sudo modprobe ax88179_178a
modprobe: ERROR: could not insert 'ax88179_178a': Invalid argument

$ dmesg # relevant part
[ 1827.985623] BPF: type_id=1113 bits_offset=0
[ 1827.986241] BPF:

[ 1827.986693] BPF:

```

### Diagnostic Logs

_No response_

Start with the WSL2-Linux-Kernel tree and Microsoft/config-wsl, then reproduce the reported build, modules_install, and modprobe sequence for CONFIG_USB_NET_AX88179_178A=m. Read the BTF validation messages from dmesg and the module-loading path; done means the built module loads successfully under WSL 2 without the reported Invalid argument error.
